使路(lu)外表沒有伸縮縫，進(jin)步行車舒(shu)服性；有利(li)于改進(jin)軟土地(di)基結構與(yu)路(lu)堤(di)交界(jie)處的(de)(de)(de)(de)“錯臺”現象，進(jin)步行車安全(quan)性。波(bo)紋(wen)管涵的(de)(de)(de)(de)工后(hou)營運、養護成(cheng)本低(di)，工程實際造價也低(di)于同類跨徑(jing)的(de)(de)(de)(de)橋(qiao)梁、涵洞。鋼(gang)板的(de)(de)(de)(de)波(bo)形(xing)為進(jin)步板的(de)(de)(de)(de)剛度，板的(de)(de)(de)(de)截面(mian)從平(ping)板加工成(cheng)必定波(bo)幅(fu)的(de)(de)(de)(de)波(bo)形(xing)狀(zhuang)，從加工、拼裝及板的(de)(de)(de)(de)剛度要求動(dong)身。

Make the road surface free of expansion joints and improve driving comfort; It is beneficial to improve the "staggered platform" phenomenon at the junction of soft soil foundation structure and embankment and improve driving safety. The post construction operation and maintenance cost of corrugated pipe culvert is low, and the actual project cost is lower than that of bridges and culverts with similar spans. The waveform of the steel plate is to improve the stiffness of the plate. The section of the plate is processed from the plate into a wave shape with a certain amplitude, and starts from the requirements of processing, assembly and plate stiffness.

并參照國內外同類產(chan)品的波(bo)(bo)形，管直徑小于1.5m的波(bo)(bo)距為125mm，波(bo)(bo)高為25mm；管直徑大于1.5m的波(bo)(bo)距為200mm，波(bo)(bo)高為55mm。波(bo)(bo)紋(wen)(wen)為圓形全體管，選用(yong)整管節拼裝、法(fa)蘭螺(luo)栓銜接。全體管銜接法(fa)蘭選用(yong)角鋼(gang)(gang)、鋼(gang)(gang)板制造，波(bo)(bo)紋(wen)(wen)板焊(han)接選用(yong)對焊(han)接頭。

緊(jin)(jin)固件選用國標中的規范緊(jin)(jin)固件，其強(qiang)度和規格(ge)應滿意力學要求，且不低于(yu)管(guan)材強(qiang)度要求。墊片與緊(jin)(jin)固件般配。螺(luo)栓與螺(luo)母(mu)均選用熱浸鍍鋅處理。密封(feng)材料(liao)選用耐(nai)久性能較(jiao)好的橡膠密封(feng)圈(quan)或(huo)方形石棉(mian)盤根(gen)密封(feng)條(tiao)。

鋼波紋管涵加工后須選用熱鍍鋅等防腐處理。選用鍍鋅鋼板加工的，在加工后進行二次處理。為便于鋼板的加工制造，結構的裝置銜接，進步鋼板的制造精度，板材的尺寸宜適應不同管徑的需求，以形成系列化。板的厚度隨結構跨徑的巨細變化，鋼板厚可選用2.5-8mm。管壁及配套附件均經過熱浸鍍鋅處理，其鍍鋅層的平均厚度大于84um.涵管運至施工現場后，工地現場涂刷兩邊瀝青。//hanihanbj.com/
